Before filling, the electrode paste shall be broken into 80 ~ 100mm small pieces, so that the electrode paste can pass between the two ribs smoothly. If the particle size is too large, the electrode paste suspension fault is easy to occur; If the particle size is too small, it is easy to cause paste spraying. It is better to buy the finished electrode paste. If the material supplied by the manufacturer is qualified, it can be directly filled. The powder of broken electrode paste is reduced, the utilization rate of electrode paste is improved, and the cost of calcium carbide is reduced. Use a forklift to transport the electrode paste to the carbide furnace with a trolley or special tools, and use an electric hoist to lift the electrode paste into the electrode barrel. Pay attention to lifting * during filling.
When installing the electrode paste, pay attention not to scatter the electrode paste on the equipment outside the electrode barrel, so as to avoid the electric ignition accident. Every time the electrode paste is filled, the site shall be cleaned, especially the electrode paste scattered on the equipment.
When adding electrode paste, it is necessary to pay attention that people do not touch the two-phase electrodes at the same time to prevent electric shock. It is also important to note that the two-phase electrodes should not be removed at the same time for conductive objects to prevent power connection.
In addition, most of the electrode pastes in China are square three pieces. It needs to be broken in use. At present, some manufacturers have improved the shape of electrode paste and made it into ellipsoid with appropriate particle size. For example, the sealed electrode paste produced by Fuzhen carbon is 72mm * 65mm * 120mm, with a mass of about 500g. It has the following advantages:
(1) Convenient loading, unloading, storage and transportation;
(2) The finished products are screened and the slag is removed in the loading and other processes for many times without weight loss;
(3) Less dust pollution, *, reliable;
(4) The particle size is moderate, and no electrode paste spraying accident will occur.
